hey there......on the site i see that the original heights for the hard top are listed, but does anyone know the original heights for the convertible, such as rear bumper to ground, or rocker panel to ground. i just pasically need to know if i lost any of the original ride height over the years and that is why i am having trouble with my new rims and tires. thanks.

Should be the same as coupe. What size wheels and tires are you having trouble with?

If you have a 69' service manual you should be able to find it in there.

Unless I'm missing something that's for all models. All models of Firebirds the same.

Yes.

What is the hub centerline height? My car has aftermarket tire/ wheel combo.

By measuring thr rockers with a shorter tire combo, the rockers are obviously going to be lower to the ground. And this car definitely has sag! So what is the stock reference point?

Thanks!!
